VPS. Everything slows down on Apache2, flies on nginx, what's wrong?

Question

Nginx

Hello.
There is a pure VPS (ubuntu 16.04) and a website/cms in php.
Set Apache2+php = everything slows down, the page is loaded in 3-5 seconds.
Nginx+php-fpm = everything flies like on localhost.
What's wrong? Please tell me, this is not the first VPS I am changing, I thought what the limits of the tariff plan are, but it turns out that Apache is like that. Configs and there and there default.

Answer 1

The config was still not default, there were my inserts from the previous vps
StartServers 1
MinSpareServers 1
MaxSpareServers 1
MaxClients 3
ServerLimit 3
MaxRequestsPerChild 300
commented out all these lines, everything worked quickly.
If someone comments on these parameters (bad or good) I will be glad, thanks

Answer 2

Well, use nginx. Level question: why do I drive so slowly on a tractor, but when I get into a Lamborghini...

Answer 3

I recommend using the Apache+Nginx bundle.
Alternatively, you can configure the config according to this instruction

Answer 4

webmaster Apache2 requires more resources. VPS does not have as many resources as on a local computer. nginx requires much less resources. That's why it's faster on VPS

Answer 5

Apache - the last century
